Céline Dion has announced her return to the stage, four years after she was diagnosed with an incurable condition that affected her singing voice and her ability to walk.

The star, known for power ballads like My Heart Will Go On and Because You Loved Me, will play a 10-night residency at the 40,000-capacity Paris La Défense Arena in September and October.

The announcement came on the day of her 58th birthday. In a message on her Instagram page, Dion called her comeback "the best gift of my life".

"I'm so ready to do this," she told fans. "I'm feeling good, I'm strong, I'm feeling excited, obviously, [and] of course, a little nervous."

Addressing her medical condition, Dion said: "I'm doing great, managing my health, feeling good. I'm singing again, even doing a little bit of dancing.

"But I have to tell you something very important: Over these last few years, every day that's gone by, I felt your prayers and support, your kindness and love.

She continued: "I am grateful to all of you. I can't wait to see you again."

High demand for tickets

Dion, who is one of the best-selling artists of all time, has not performed her own show since Newark, New Jersey on 8 March, 2020.

Her Courage tour was subsequently cut short by the outbreak of the Covid pandemic, before she was diagnosed with Stiff Person Syndrome and forced to cancel all future shows.

For her live return, all the concert dates are separated by several days, presumably to avoid undue strain on her physical health.

Tickets will go on sale from 7 April. Demand is expected to be astronomical, but fans can register interest on her official website from Tuesday, 31 March.

Plans for the comeback were initially leaked by the French-Canadian newspaper La Presse last week.

Soon afterwards, fans spotted posters featuring Dion's lyrics popping up around the French capital.

On Monday night, shortly after 8pm GMT, the Eiffel Tower lit up with the message, "Paris, je suis prête" (Paris, I am ready), and fans were treated to a playlist of songs including I'm Alive, Encore Un Soir and My Heart Will Go On.

Dion also recorded a French version of the video message announcing the tour, which was played over loudspeakers as the Tower was illuminated by purple lights.

Difficulty walking

Dion announced she had been diagnosed with Stiff Person Syndrome (SPS) in December 2022.

In an emotional Instagram video, she told fans the condition had affected "every aspect of my daily life".

Affecting an estimated 8,000 people worldwide, SPS is a neurological disease in which signals from the nerves to the muscles do not work properly.

The condition causes muscle spasms and can affect mobility. For some, it can be debilitating. There is no known cure.

Speaking to the BBC in 2024, Dion said she first noticed the symptoms when her voice started to play up on tour.

"It was just feeling a little strange, like a little spasm," she said.

"My voice was struggling, I was starting to push a little bit."

At the time, she felt it was impossible to take time off, and experimented with singing in a lower register to ease the stress on her vocal cords.

"These shows were sold out for a year and a half, going around the globe.

"And I'm going to say to people, 'Excuse me about my spasm? Excuse me about my je ne sais quoi?'"

However, the condition worsened, "sometimes causing difficulties when I walk and not allowing me to use my vocal cords to sing the way I'm used to," she told NBC News.

"It's like somebody is strangling you. It's like somebody is pushing your larynx [or] pharynx."

However, Dion was determined not to let SPS rule her life.

In 2024, she told French Vogue magazine about the intense efforts she had made to combat the disease.

"The way I see it, I have two choices. Either I train like an athlete and work super hard, or I switch off and it's over," she said.

"I've chosen to work with all my body and soul, from head to toe, with a medical team.

"Five days a week I undergo athletic, physical and vocal therapy. I work on my toes, my knees, my calves, my fingers, my singing, my voice."

The efforts paid off. Dion made an emotional comeback at the 2024 Paris Olympics, singing Edith Piaf's classic Hymne à l'Amour from the Eiffel Tower.

That was also the first song played as her comeback shows were announced at the Eiffel Tower.

The Canadian star has long had an affinity for the city.

"I want to love more when I'm in Paris," she told Vogue in 2024. "It makes me love things more."
